HAY-COOKING MACHINE.

Specification ot' Letters Patent. Paiglilfd July 1 2, l 'ill t?.

Application filed January 11, 1910. lSerial No. 537,530.

To all whom 'it may concern:

Be it known that I, GEORGE iViLLLiM LATTA, a citizen of Canada, residing at Corbyville, in the Province of Ontario and Dominion of Canada, have invented new and useful Im Jroveinents'in Hay-Cooking Machines, of w ich the following is a speciication.

The present invention provides a machine of novel formation for use in the field for gatheringhay, .st-raw, grain, and the likelshock formeris thrown into gear to be actuated for deposit-ing the shock upon the ground the frate is at the same time closed, thereby pre'el'itingA discharge ofthe material and whereby when the shock former is about at the limit lof vits return movement after discharging the shock upon the ground thc gate is automatically opened to admit of the material discharging. from the carrier into the shock former. I

A` further purpose of the invention is to providea carrier of peculiar formation and l arrangement; for positively urging the grain forward afterthe same has been picked up and elevated, said meclmnism serving to pack or condense the librous material, so that it mai/,pack to better advantage in the sh ook' former.

The invention also aims to improve the momitiugs of the'scvcral parts and to devise a trip mechanism automatic in operation for etlcctingan opening of the gate by meansl of the shock former operating l'ncchanism just. prior to the return of the shock former to normal. position.

The invention consists of the novel teatures, details 'of-constrl-u'tion and combination of parts, which hereinafter will be more particularly .set f( .'th. illustrated in the accompanying drawings, and pointed out iu the appended claims.

Referring to the drawings, forn'iing a partof the specification, Figure l is a side view of a shock forming machine embodying the invention. Fig. 2 is a view similar to Fig. l, showing the elevator and carrier in section and the position of the shock former on its return to normal position after having deposited a shock upon the ground. v Fig. 3 is a rear view of the machine, a port-ion of the main frame being broken away. Fig. 4: is a detail horizontal section on the line LiL-lof Fig. l, showing the parts on a larger scale'.

Fig. 5 is a sectional viewof the same partsI shown in Fig. 4, bringing out more clearly the structural details. Fig. 6 is a sectional detail on the line 6 6 of Fig. 4, looking to the left. Fig.'7 is a detail perspective view of the bracket provided with t-he cam and the dog pivote-d thereto. Fig. 8 is a detail section of the shock former mounting on the line 8-8 of Fig. 3.

Corresponding and like parts are referred to in the following description, and indi- :ated in all the views of the drawings. by the' same reference characters. The main frame is mounted upon a tasty vQteel 1 and ground wheels 2, the latter corfstl uting drivers for operating the working parts. The main frame ,comprises side v pieces 3, an arch Il connecting the rear ends of the side pieces 8 and a draft fraiie 5, the latter haring the" team hitched thereto for propelling the machine over the ground. Arms G extend. upwardly from the side and support the framework of the pieces E) elevator and carrier. The drive wl'1cels'-2 are mounted upon the arms of the axle 7 so I as to rotate the axle and th'c sprocket wheels fastened thereon and from which )ower is taken for driving the elevator am carrier and actuating the shock formerY and parts cooperating tlurewith. l

'.lhe shock former- S consi-sts of a receptacle ol"l approximately corneal form and isl mounted to receive both arota-ry motion about a vertical axis and a turning about a horizontal axis. the latter rcsultingin discharging the shock al'ter the same hasbeen formed. frame 9 supports the shock former or receptacle 8 and is mounted to turn about a horizontal axis, the shook former being mounted upon the frame 9 soas' to turn thereon about ay vertical axis. The frame 9 is provided at diametrically opposite points with trunnions 10, which are mounted in bearings of the main frame. A duplex sprocket wheel is loosely mounted upon one of the trunnions 10 and com rises the s rocket wheels 1.1 and 12, whicli are holte( or otherwise secured together with a collar 13 of the trunnion 1() confined between them, so as to prevent longitudinal `n'ioven'ient of the duplex sprocket wheel upon 'the trunnion. It is to be understood in this connection that the duplex 4sprocket wheel may bc formed in any manner and mounted upon the trunnion 1() so as to rotate freely thereon yet be prevented from moving longitudinally thereon. A clutch member 14 is provided upon the outer side of the duplex sprocketl wheel and is adapted to cooperate with'- a clutch member 15 mounted upon. the trunnon and secured thereto by means of a feather and Spline connection, so'as to turn therewith and yet be free to move longitudinally thereon. A helical spring 16 mounted upon the trunnion 10 normally exerts a pressure uponl the clutch member 13 to force the same into engagement with the clutch member 14. A shipper lever 17 pivoted at one end to an arm 18 secured tothe tvuhnion 10 has engagement with the movable clutch member '15 and is adapted to be held in restraint at its opposite end `so as to hold the clutch members 14 and 15 separated," so that the duplex sprocket wheel may turn freely upon the trunnion 10.

A bracket 18 is secured to a side'p'iece" of the main frame and is provided with a cam` 19, which'extends across the path of the free end of the shipper lever 17 so asto move the same outward and compress the spring Ward to keep the c utch members 14 and 15v separated.

The' outer end of the clutch lever is confined between projecting parts of the .per leversecurely against rotary-movement i keep the clntch members 11' and 15 separated'r on withdrawal of the dog 20, from t glhhd theshipper lever 17, the spring 16 ,'ini either-direction when it 1s required to cornes into play 'and moves the clutch in emer 15 yinward into engagement with the clutch member 14, with the result 4that the ,duplex sprocket wheel is keyed to the trun- 'n-io'n' 1'0 and the frame 9 is caused to rotate, thereby inverting the shock former 8 and ol'icrating mechanism may be thrown into gear to effect discharge of the shock in the manner stated.

'l`he connection 24 between the dog 2() and hell crank 22 may consist of a rod or analogous part. ',lhe other member of the bell crank 22 constitutes a treadle -upon which the driver exerts pressure by meansrof the foot. When the duplex sprocket wheel is secured to the trunnion 10, by means of the clutch, the trame 9 and shock former move forwardly and downwardly. The arm 18 being secured to the trunnion rotates therewith, hence the shipper lever 17 pivoted to the ,arm 18 and receiving the truunion 10 s and clutch member 15, whichpasses hrongh an opening thereof, correspondingly rotates and when the shock former is approaching the` limit of a complete revolution the free end of the shipper lever 17 engages the cani 8 1U and rides thereoh, with the'rcsult that the outer end ot' the shipper lever is moved outward and carries the clutch member 15 therewith, the parts heilig so timed and pro' portioned that when the shock former is in 9i normal position the clutch member 15 is completely disengaged from the clutch meml ber 14 and its outer end is held secure tween the projecting parts of the ca and the dog 20. f A

The cock or shock former 8 is mounted upon the frame @so aste turnfreely about a vertical axis and 'is provided at its lower end with' a bevel gearV 25,` whic1i vmeshes with a bevel gear 26 mt'the inner end4 of 'aA horizontal 'shaft Y27, the latter being p'ro: vided at its outer end with a sprocket wheel 28, which is connectedby sprocket chain 2 9 with the sprocket wheel 11. By this means 4motion is transmittedfrom the du ple'x sprocket wheel to theshock former for rotating-'the latter Iabout a v'e'rtical'axis. The shock former, is provided intermediate of its upp'er and lower ends with a hand v 30. and with a circular trackl, the latter 1l( being secured to `thefshock former atintervals by means of brackets 32 A circular track 33 of angle formation iny transverse section is secured to upright menibersof the frame t) and forms a .part thereof, The 115 space inclosed between 'the --band .30T fand tracks 31 and 33 forms a race in'whichba'lls 34 are placed and which cooperate with the inclo'sing walls of the race to retain the i shock formerv in place and iedneethe fric tion to the smallest ,amount pbssible l Slnocket wheels 35' are secured to opposite y 'end portions of the axle 7 so as to rotate' therewith, one of thesprocket wheels being single und the other double. A sprocket 125 chain St'connects a member of the. double sprocket wheel with` the sprocketfwhel 12,

material in the carrier and pies an in the shock former 8 is caused to rotate about a vertical axis by reason of the intermediate connections between the double sprocket wheel 35 and the shock former 8. When suliicient material has accumulated in the shock former to providea shock ot' the Llc-- sired dimensions `the bell crank or foot lever `Q2 is operated, thereby 4throwlng the clutch into engagement in themanner hereln stated.

with the result that the shock former carry which are mounted upon crank portions of crank shafts 40 and 4l. The vibrating rakes 39 operate alternately and serve to move the material upward through the trough-shaped frame 38 step by step. The carrier consists of a trough-shaped frame 42 and'toothed bars 43, the latter being mounted upon crank portions of the shaft 40 and a crank shaft 44, the latter being mounted near the vrear end of the frame 42. The crank shaft 40 is positively driven from the axle 7 by means of sprocket chains 45, ,which pass around the sprocket' wheels 35 and other sprocket wheels 46 secured to opposite ends of the crank shaft 4,0. The carrier 42 is ar- 'ranged in an approximately horizontal position, its 'rear end terminating above the shock former, so that the material discharging from the carrier drops directly into the shock former. A gate 47 closes the rear end of the carrier or frame 42 and is' adapted to swing upward and rearward from its lower edge. During theformation ot' the shock the gate is open, as indicated hy the full lines in Fig. 1, and when the shock former is turning with its supporting frame 9 to discharge the shock the gate 47 is closed, as indicated in Fig. 2, thereby retaining the preventing waste thereof?l l i An aren 4S is seciared at one end fto the gate 47 and extends outwardly therefrom, passing through a bracket 49 secured to lsaid gate." A spring` 50 connects' the outer end of the arm 48 with the carrier 42, the parts being so arranged thatwhen the gate is closed the spring 50 exerts a .force to hold Said gate shut, and when the gate is open the spring exerts a pressure to retain saidv lgate 1n itsio en position. This is plain on reference to' t igs. 1 and Zofthe drawings. When the gate is closed the spring 50 occue med positionandexerts a pulll ing force to force the gate against the frame or carrier 42 and when said gate is open the spring 5() occupies an approximately vertical position and exerts a pulling torce to throw the gate upward, as indicated by the full lines in Fig. 1. The bracket 49 lsecured to the gate inclines upwardly and rear- Fig. 2, and inclines upwardly land forwardly when the gate is open, as indicated in 'Fig'. l. hence the relative position of the spring 5U changes under the `varying conditions.

A bell crank 51 is mounted upon the np.- per portieri of the elevator frame 38 and one member is connected by means of-a rod or ber is connected-by means of a bar or rod 53 with'- the bell crank or foot lever 22. At the same time that the bell crank or foot lever 22 is operated to withdraw the dogrQO from beneath the free end of the shipper lever 17', the bellvctank 5l is o er'ated t0 throw the gate 57 Iopen. vIt wil thus be formed practically at the same time. A bar. or rod 54 is connected at itsupper end to van arm 55 secured-to an extension of the axis or journal ofthe gate 47 and its lower end extends into the path of the shipper lever 17 and is-provided with a hook 56 to to be engaged by a pin 57 projected laterally from the free end of the'gshipper lever. A bracket arm 58 extends from the main frame and its upper end is provided with a slot 5,9, through white the bar or rod 54 passes. A vspring 60 secured to the bracket 18 extends -into the slot 59 and presses against the lower end of the bar or rod 54 to hold'the same at the outer end of the slot 59 and in position to be engaged by the pin or projection 57 of the shipper lever. When the gate 47 is closed, as lndicated by the dottedv lines in Fig.l 1 and by the full lines in Fig. 2,?-Eithe bar or' rod 54 is elevated, so that its hcokedend 56 is in a position 4to be engaged by the pin orproje6tion 57 of the shipper lever just prior to the return of the shock former 8 to normal position. The pin of the bar 54 a little in advance of engagewith the cam 19, so that the arn. 55 is drawn downward, thereby opening the gate 47 and at the same time moving the parts 49 and 48 untilV the upper rend ai the spring 5d passes by a line extending perpendicularly throw the gate 47 open to its fullest extent. As the shipper lever v17 rides upon the cam 19 it is moved outwardly at its free end, thereby withdrawing the pin or projection 57 from engagement with'thehooked end of the bar or rod 54, so as to clear the same a moment before the shipper lleverpasses wardly when the gate is closed, as shown in` bar 52 with the gate 47and its other mem-l ment of the free end of the shipper lever understwd that both operations are peror projection 57 engages the hooked end 56 i throughthe' axis of the gate, when said spring, by reason of its tractile force, will thecam lf). It will thus-be understood that the gate '4T is opened automatically and at the .proper tiine,`the gate opening means bc.- ing thrown out of action at about the same `E time, that the' shock tormerassumes the giver."position. v In'the practical operation of the invention the hay or other fibrous material ie gathered by tlierake 37 as themachine is lo drawn over the tield and is lifted tothe carier 42 by means of the elevator and is discharged from said .carrier and drops into the shock former, the latter being continuously rotated Vto insure an even distribution i of the material' therein. After tlie receptau n cle or ehock former 8 has received euilicient material to form a shock'the driver operates the bell crank'or foot lever 22, thereby closing the gate 47 and atth'e saine time throw*- ing the mechanism into gear for rotating the shock `former about a horizontal axis to effect a'fdiecliargey `ofthe shock, upon the ground."
